FRANK F. TURNER, OF LITTLE FALLS, MINNESOTA.

WHEAT-HEATER, GRAIN-DRIER, AND CONDITIONER.

Application filed May 1, 1912.

To all whom/1f may concern:

Be it known that I, FRANK F. TURNER, a citizen of the United States,residing at Little Falls, in the county of Morrison and State ofMinnesota, have invented certain new and useful Improvements in VVheat-IHeaters, Grain-Driers, and Conditioners, of which the following is aspecification, reference being had to the accompanying drawings.

lThis invention relates to new and useful in'iproifements in graindriers and has for its object to provide an improved device of thischaracter wherein steam is provided as a means for the drying of thegrain.

A further object of the invention resides in providing` a casing orhousing having a series of pans alternately inclined in oppositedirections, said pans having hollow portions for the reception of steam,and still another object resides in the oscillation of the casing orhousing carrying this series of pans.

Another object resides in providing a device which is extremely simpleand durable in construction, inexpensive to manufacture and one whichwill be very efficient and useful in operation.

Vith these and other objects in view, the

' invention consists in the novel features of construction, combinationand arrangement of parts as will be hereinafter referred to and moreparticularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure1 is a perspective view of tlle device having the wall of the outerframe, nearest the observer, removed. Fig. 2 is a vertical longitudinalsection through the device. Fig. 3 is a vertical transverse sectiontherethrough. Fig. 4 is a plan view of the device partly in section.

In describing my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates an outer frame or housingwithin which is adapted to be disposed my improved grain drying andsteaming chainber. This chamber comprises a housing or casing 2 havingthe inlet and outlet openings 3 and t respectively provided at the upperand lower portions of the same and mounted in said housing is a seriesof hollow pans or the like 5 which are disposed Specification of LettersPatent.

one above the other and are alternately inclined in opposite directions.The inlet opening of the housing communicates with the upper portion ofthe upper inclined pan 5, while the outlet opening 4 is positionedimmediately below the lower portion of the lowermost of said pans 5,whereby grain may be entered from a hopper or the like through the inletopening to each successive pan and be finally passed to the outletopening 4 and in order to cause the grain to be turned as the samepasses over the upper faces of the inclined pans, each of said pans isprovided adjacent its upper or inner portion with one or morecorrugations 6.

As stated, the pans 5 are hollow in design, tlie grain passing over thetop face thereof, and disposed on one side of the chamber 2 is a steaminlet pipe 7 which has a plurality of branch pipes 8 formed thereonwhich is disposed laterally thereof and extended beyond the wall of thechamber to enter the various hollow pans 5 adjacent their upper inclinedends. Disposed on the opposite side of the housing or casing 2, is anoutlet steam pipe 9 which communicates through the medium of a plurality of branches 10 with the opposite sides of the hollow pans 5adjacent the lower inclined ends thereof. The ends of these steam pipes7 and 9 having engaged therewith the flexible connections 11, whichrespectively lead to a source of supply and exhaust outlet. The steam,under pressure flowing through the pans 5 will, of course, have atendency to dry the grain as the same passes over the Lipper faces ofsaid pans. As stated above, this chamber 2 is disposed within the frameor outer casing 1 and in order to provide for the suspension of the sameto permit oscillation thereof, the inner side faces of the upper portionof said frame are provided with sockets 12 which receive therein, thesuspension rods 13, which are formed of spring metal, said rods beingheld to the sockets by means of the adjusting screws 14. Similar sockets15 are provided on the outer faces of the chamber 2 adjacent the lowerends thereof, said sockets receiving in adjustable engagement therewith,the lower' ends of said suspension rods 13, and from this constructionit will be seen that said housing of casing 2 may be suspended withinthe frame 1 and be permitted to oscillate therewithin.

In order to provide for the oscillation of the chamber within the outerhousing or casing 1, so that t-he grain passed therein may readily passfrom one pan to the other, a shaft 16 rotatably mounted in bearings 17,on one wall of the frame 1, has a pulley 18 carried at one end thereo-fwhich communicates with any desired source of power. This shaft 16 has acrank 19 formed thereon which connects with one end of a pitman 20, saidpitman extending through a slot 21 in the adjacent wall of the frame orhousing 1 and the opposite end of said pitman is pivotally engaged in abearing or the like on the one end Wall of the housing 2, wherein itwill be appreciated that as the shaft 16 is rotated, said casing 2 willbe oscillated within the frame 1.

From the foregoing description of the construction of my device, theoperation thereof will be readily understood and it will be seen t-hat Ihave provided a simple and eicient device which is extremely durable inconstruction and inexpensive to manufacture.

While I have particularly described the elements mo-st well adapted toperform the functions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may beresorted to without departing from the spirit or sacrificing any of theprinciples of the invention.

Having thus described my invention, what I claim is 1. A. grain driercomprising a main frame, a housing, means for oscillating said housing,a plurality of hollow pans mounted within said housing, the pans beingalternately inclined in opposite directions and having theircorresponding side faces formed adjacent their upper ends with intakeopenings, the opposite side faces of said pans being formed adjacenttheir lower ends with outlet openings, means connected with said intakeopenings to supply a heating medium directly to each pan, and meansconnected with said outlet openings for withdrawing said heating medium.

2. A grain drier of the class described, comprising a plurality ofhollow pans, means for oscillating said pans the pans being oppositelyinclined in opposite directions and having their corresponding sidefaces formed with intake openings adjacent the upper ends thereof, theopposite side faces of said pans being formed adjacent their lower endswith exhaust openings, a supply pipe having a plurality 'of lateralprojections, each of said projections communicating with one of saidintake openings, and an exhaust pipe formed with a plurality of lateralprojections, each of said last mentioned projections communieating withone of the aforementioned exhaust openings, for the purpose specified.

In testimony whereof I hereunto my signature in the presence of twowitnesses.
